From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Did you change the gtk theme recently? Firefox follows the gtk3 titlebars, not the qt ones. You would have to change the gtk3 theme back to breeze to have it match again.
If you changed off the default firefox theme, it will also no longer use native titlebar buttons, to make it use native ones with a different firefox theme, go to about:config, search non-native, find the titlebar buttons option, and turn it off.
My GTK Theme is already set to breeze:
Changing the value in about:config had no effect. Thanks anyway though!
